So I am home for spring break in lovely Cleveland, OH (not... it's cold here dude!)  My parents seem to have acquired an interesting visitor this past week.  It's an American Robin and probably a male from the way it's behaving.  What's happening is that it is continuously flying into the window of our computer room, over and over again.  We put curtains up because I figured the reflection of the trees on the glass was making him do it, but that didn't help.  Finally, after watching him for a while and observing his body language, I think I have figured out just what he's up to: he sees another bird in the glass, and this bird is a rival male!  Unfortunately, for some strange reason this other male won't back down to his "fearless charges," and can somehow predict and counter his every move.  He has been fighting with the window for three days straight now!  He charges it, beats it with his wings, and even lands on what little windowsill we have and pecks at his reflection!  Funny though the entire performance is, I feel bad for the guy, and I am afraid he is going to hurt himself!  Has anyone witnessed this crazy display before, and if so, how long did it last?  I am assuming it will last another few weeks at least, or until his reflection defeats him.  Until that time we have christened him Timmy, after the Southpark character of that name.  I went outside today to watch him and told him he was an embarassment to his species, to which he replied by smacking against the window one more time.
